Planet FGSD-1821P

Physical Port

• 16 10/100BASE-TX RJ45 ports with IEEE 802.3at PoE+ injector function (ports 1~16)
• 2 10/100/1000BASE-T Gigabit RJ45 ports interfaces (ports 17~18)
• 1 1000BASE-X SFP interface (port 17)

Power over Ethernet

• Complies with IEEE 802.3at Power over Ethernet Plus end-span PSE
• Up to 16 ports of IEEE 802.3af/802.3at devices powered (ports 1~16)
• Supports PoE power up to 32 watts for each PoE port, with a total PoE budget of 185W
• Each port supports 55 DC power to PoE powered device
• Auto detects powered device (PD)
• Supports PD alive function
• Circuit protection prevents power interference between ports
• Remote power feeding up to 100m in standard mode with 250m in extend mode

Switching

• Hardware-based 10/100Mbps and 10/100/1000Mbps auto-negotiation and auto MDI/MDI-X
• Supports IEEE802.3x flow control in full-duplex mode and backpressure in half-duplex mode
• Integrates address look-up engine, supporting 16K absolute MAC addresses
• 16K jumbo frame supports 1000Mbps speed
• Hardware-based DIP switch for Standard, VLAN or Extend mode selection
  • VLAN mode: Ports 1 to 16 cannot communicate with each other, but can communicate with the uplink ports 17 to 18 and SFP port 17
  • Extend mode: Ports 1 to 8 have data rate of 10Mbps. The farthest transmission distance is up to 250 meters and all ports can communicate with each other
• VLAN mode is to isolate ports to prevent broadcast storm and defend DHCP spoofing
• Automatic address learning and address aging
• Supports Energy-Efficient Ethernet (EEE) function (IEEE 802.3az)

Hardware

• 11-inch desktop size, 1U height
• LED indicators for system power, per port PoE ready and PoE activity, speed, link/act
• 1 silent fan to provide stable and efficient power performance
• Supports contact discharge of ±6KV DC and air distance discharge of ±8KV DC for Ethernet ESD protection
• Supports ±6KV surge immunity
